One of the major improvements recently made to ROBOTC was the ability to “Automatically Update the VEX Cortex” and “Automatically Update the VEXnet Joystick”.

The new functionality has been very well received, saving Cortex users lots of time and effort. To reflect the improvements in ROBOTC, we’ve updated the Setup materials in the VEX Cortex Video Trainer.

We’ve also simplified the Cortex setup process by splitting the instructions into two tracks: wireless and wired instructions. The new materials can be found in the Setup > System Configuration section.

Good news everyone! I’m excited to let you know that our latest batch of tutorials in the VEX Cortex Video Trainer are available now!

This set of 5 tutorials focuses on the VEX Line Tracking Sensors:

The Line Tracking Sensors – Introduces the sensors and explains how they work

Calculating Thresholds – Goes through the process of acquiring sensor values using the ROBOTC Sensor Debug window and calculating a threshold for the robot to distinguish light from dark

Basic Line Tracking – Opens, explains, and runs a basic line tracking sample program on the robot

Line Track for Distance – Modifies the sample program to line track for a number of encoder counts

Optimized Line Tracking – Explains how to modify motor speeds for tracking different types of lines

These tutorials will work with the new VEX Line Tracking Sensors (in the picture above), as well as the slightly larger, previous generation. To view them, open the VEX Cortex Video Trainer and head to the Sensing > Line Tracking section. Be on the look-out for additional programming challenges and activities using the line tracking sensors early next year.

As usual, the VEX Line Tracking Sensors can be purchased at the RobotMatter store. Happy Holidays everyone!
